Alpsport Badminton Training Racket – Technical Overview

This racket is engineered for repetitive stroke practice, offering a balanced mass distribution that reduces wrist fatigue during extended training sessions.

Design and Materials

The frame utilizes a high-modulus graphite composite with a tensile strength of approximately 4.2 GPa, providing stiffness that minimizes energy loss on impact. The shaft incorporates a tapered geometry, decreasing from 28 mm at the throat to 22 mm at the tip, which shifts the balance point toward 290 mm from the handle end.

• Frame material: 80% graphite / 20% carbon nanotube reinforcement
• Shaft material: 70% graphite / 30% aramid fiber for vibration damping
• Grip: synthetic PU with a perforated surface, thickness 1.2 mm

Performance Characteristics

Measured swing weight falls within 78‑82 g·cm², suitable for rapid forehand and backhand drills. The string bed accommodates tensions from 20 lb to 28 lb, allowing coaches to adjust shuttlecock rebound speed without altering frame geometry.

Natural frequency of the racket, determined via modal analysis, is approximately 115 Hz, indicating a stiff response that aids in consistent shuttle placement during multi‑shuttle feeding.

Typical Specifications

Applications in Training

Coaches select this model for multi‑shuttle feeding because its low torsional twist (measured at 1.8° under a 5 Nm torque) maintains racket face orientation, reducing variability in shuttle trajectory. The moderate head‑light balance facilitates quick wrist snap for net‑kill practice while still delivering sufficient power for clear‑shot repetitions.

Durability testing shows less than 5 % loss in frame stiffness after 10 000 impact cycles at 25 lb string tension, indicating suitability for high‑volume training environments such as club academies and national team preparation camps.

Quality Assurance and Testing

Each racket undergoes a three‑stage inspection: dimensional verification (±0.5 mm on length and width), static flexural load test (200 N applied at the throat, deflection recorded <2.3 mm), and impact resonance analysis to confirm natural frequency within 110‑120 Hz range.

Batch‑level sampling includes a 10‑piece pull test on the grip adhesive, requiring a minimum peel strength of 1.2 N/mm to ensure grip integrity during prolonged sweat exposure.

Customization Options

Buyers may request adjustments to grip circumference (range G3‑G5), shaft taper ratio, or paint finish without altering core layup. Lead time for customized units averages 18‑22 working days, contingent on material availability.
